Abstract
The present invention relates to flame detection apparatus and method. The present invention provides a method and apparatus for monitoring the status of a combustion unit having at least one bumer. Initially, a digital image of a flame corresponding to a flame is acquired. Next, a value for the relative light intensity of a frame defining an area of the image corresponding to the flame for the burner is calculated. The relative light intensity value is compared against a tolerance range for the frame. If the relative light intensity value is outside the tolerance range then an alarm state output is generated.
